FIG. 6 is a schematic block diagram for explaining a cable management control system (1000) for underground distribution using a cable fixing device (10) according to one embodiment of the present invention. FIG. 7 is a schematic block diagram for explaining the detailed configuration of a detection control unit (400) according to one embodiment of the present invention.

A cable fixing device (10) installed in an underground distribution line according to one embodiment of the present invention can be configured to clamp and fix a cable (1) of an underground distribution line, i.e., an underground distribution line, to one area, and also to interconnect a plurality of cables (1). In addition, an underground distribution cable management control system (1000) using a cable fixing device (10) according to one embodiment of the present invention can be configured to detect in real time current leakage and ignition occurring in an area of the same length of a single cable (1) to be clamped and a plurality of cables (1) arranged in parallel.

A cable fixing device (10) according to one embodiment of the present invention may include a rail unit (100) that is formed to extend to a predetermined length and has a plurality of sliding fixing grooves (110) formed at predetermined intervals, a sliding fixing unit (200) that is configured to slide and engage along the longitudinal direction of the rail unit (100), and a clamping unit (300) that is coupled to at least a portion of the sliding fixing unit (200) and has a circular groove (321) for cable fixing through which a cable (1) passes.

First, as illustrated in FIG. 1, a rail unit (100) according to one embodiment of the present invention may be formed with a wall attachment surface (120) that is attached to one wall surface of an installation environment on one side, and may have sliding fixing grooves (110) that are dug to a predetermined depth in a width direction perpendicular to the longitudinal direction of the rail unit (100) on the other side and continuously arranged at a predetermined interval, and may have fixed unit fastening portions (130) that are formed by protruding laterally at both ends of a plurality of raised protruding areas forming the sliding fixing grooves (110), so that when the sliding fastening portion (210) of the sliding fixing unit (200) is caught on the fixed unit fastening portion (130), the sliding fixing unit (200) can slide along the longitudinal direction of the rail unit (100).

In addition, as exemplarily shown in FIG. 4, the rail unit (100) according to one embodiment of the present invention may be composed of a bendable flexible material (e.g., silicone or rubber material, etc.). Accordingly, the rail unit (100) may be bent and adhered to the installation surface not only when the installation surface of the underground distribution line installation environment to which the rail unit (100) is attached is flat but also when the installation surface is curved.

A sliding fixing unit (200) according to one embodiment of the present invention may include a sliding fastening portion (210) configured to be slidably coupled to both ends of the rail unit (100) and a unit coupling through-hole (220) configured to be coupled to at least a portion of the clamping unit (300). That is, as illustrated in FIGS. 1 and 2, the sliding fixing unit (200) may have a ‘ㄷ’ shape and may be coupled to the rail unit (100) with the open portion facing the rail unit (100), and may be provided with a sliding fastening portion (210) configured to hold a fixed unit fastening portion (130) formed at both ends of the rail unit (100) at both ends forming the open portion. Accordingly, the sliding fixing unit (200) can be prevented from being removed while the sliding fixing unit (200) is coupled to the rail unit (100) by the sliding fixing unit (210) holding the fixing unit fixing unit (130).

In addition, a unit-joining through-hole (220) to which a clamping unit (300) is detachably coupled may be formed in at least a portion of the central surface of a sliding fixing unit (200) having a 'ㄷ' shape. For reference, the fixing unit coupling portion (310) of the clamping unit (300) may have a convex spherical shape on one side and a cylindrical shape on the other side, but the diameter of the cylindrical shape on the other side may be formed to be smaller than the diameter of the convex spherical shape on the one side. Accordingly, the cylindrical shape on the other side of the fixed unit coupling portion (310) can pass through the unit coupling aperture (220) on the inside of the sliding fixed unit (200) and penetrate in the outward direction, and also, by forming the diameter of the spherical shape on one side of the fixed unit coupling portion (310) larger than the diameter of the unit coupling aperture (220), the spherical shape on one side of the fixed unit coupling portion (310) can be prevented from being separated by passing through the unit coupling aperture (220) of the sliding fixed unit (200).

In addition, a fixing pin fastening hole (230) into which a sliding fixing pin (240) can be inserted and fastened may be formed on each of both sides of the sliding fixing unit (200). Accordingly, when the sliding fixing unit (200) is coupled to the rail unit (100), the sliding fixing pin (240) can be inserted and fixed into the sliding fixing groove (110) of the rail unit (100) by passing through the fixing pin fastening hole (230). That is, by coupling the sliding fixing unit (200) that slides along the longitudinal direction of the rail unit (100) to at least a portion of the rail unit (100) and inserting the sliding fixing pin (240) into both the fixing pin fastening hole (230) and the sliding fixing groove (110), the sliding fixing unit (200) can be stably fixed and installed in one area of the rail unit (100).

A clamping unit (300) according to one embodiment of the present invention may include a fixing unit coupling portion (310) configured to be penetrated and fastened to the unit coupling through-hole (220), a clamping body portion (320) having a spherical shape and having the fixing unit coupling portion (310) coupled to at least a portion of the clamping body portion and having a circular groove (321) for cable fixing formed in at least a portion of the clamping body portion (320), a first connecting portion (330) detachably coupled to one area of the clamping body portion (320), formed to extend to a predetermined length, and having one end in a spherical shape, and a second connecting portion (340) detachably coupled to the other area of the clamping body portion (320), formed to extend to a predetermined length, and having one end configured to receive at least a portion of the spherical shape of the first connecting portion (330). A spherical receiving space may be formed inside the clamping body portion (320) of the clamping unit (300).

That is, as described above, the fixed unit joint (310) may be formed in a spherical shape with one side positioned inside the sliding fixed unit (200) and the other side formed in a cylindrical shape with screw threads formed to be inserted into and fixed in the clamping main body (320).

According to one embodiment of the present invention, a circular groove (321) for fixing a cable (1) may be formed on both sides (for reference, the front and rear sides in FIGS. 1 and 2) of the clamping body (320). As shown in FIG. 2, the clamping body (320) may be formed by dividing into two units, and each of the divided parts may be configured to be mutually fitted and coupled. That is, the entire clamping body (320) may be formed by coupling a first clamping body (320-a) and a second clamping body (320-b) that are formed by dividing into two units. Accordingly, the cable fixing circular groove (321) may be formed by mutual coupling between the first cable fixing semicircular groove (321-a) and the second cable fixing semicircular groove (321-b) which are formed by digging a semicircle shape at one end of each of the two divided units, i.e., the first clamping main body (320) and the second clamping main body (320).

In addition, the clamping body (320) may be provided with a connecting portion fixing groove (322) configured to allow a first connecting portion (330) and/or a second connecting portion (340) to be removably coupled in each of four directions (i.e., left-right and up-down directions in FIGS. 1 and 2) perpendicular to the direction of the cable (1) passing through the clamping body (320). For reference, it goes without saying that a fixing unit coupling portion (310) may be removably coupled in the connecting portion fixing groove (322) in the direction of the rail unit (100).

According to one embodiment of the present invention, a first connecting portion (330) may be configured with a first main body connecting portion (332) having a cylindrical shape with screw threads formed therein to be inserted and fixed into a connecting portion fixing groove (322), and a spherical insertion fastening portion (331) having a diameter larger than that of the first main body connecting portion (332). For reference, the first connecting portion (330) may have the same shape as the fixing unit coupling portion (310), but is not limited thereto and may be implemented in various shapes that enable coupling between units.

In addition, the second connecting portion (340) according to one embodiment of the present invention may be configured with a second main body connecting portion (342) having a cylindrical shape with screw threads formed to be inserted and fixed into a connecting portion fixing groove (322) and an accommodating fastening portion (341) having a hemispherical receiving area formed to receive at least a portion of the insertion fastening portion (331) of the first connecting portion (330). Accordingly, as illustrated in FIG. 4, the first connecting portion (330) and the second connecting portion (340) are connected to each other at a predetermined angle, so that the clamping units (300) can also be connected to each other at a predetermined angle. That is, the cable fixing device (10) according to one embodiment of the present invention may be characterized in that the bending angle between the first connecting portion (330) and the second connecting portion (340) of the plurality of clamping units (300) mounted on the rail unit (100) is set corresponding to the degree of bending of the rail unit (100).

In addition, as illustrated in FIG. 3, by connecting a plurality of clamping units (300) according to one embodiment of the present invention, each of a plurality of cables (1) can be stably fixed in parallel at a predetermined interval from each other, and further, by sequentially mounting a plurality of clamping units (300) according to the length region of the cable (1), the entire length of a single cable (1) having a predetermined length can be stably fixed.

Referring to FIG. 5, a clamping unit (300) according to one embodiment of the present invention may include a plurality of elastic support units (350) provided inside the clamping main body (320) and configured to elastically support the cable (1) passing through the clamping main body (320), and a plurality of protruding sensors (360) formed to protrude a predetermined length from the inner surface of the clamping main body (320) toward the cable (1) passing through the clamping main body (320).

More specifically, the elastic support unit (350) according to one embodiment of the present invention may include a rotary member (351) configured to rotate by contacting the cable (1) entering the inside of the clamping body (320), and a first roller member (352) configured to rotate by contacting and engaging with the rotary member (351) when the rotary member (351) rotates in one direction. In addition, the elastic support unit (350) may further include a second roller part (353) configured to rotate with a rotation axis that is perpendicular to the rotation axis of the first roller part (352), so that when the cable (1) passing through the cable fixing circular groove (321) rotates in place around the rotation axis in the longitudinal direction of the cable (1), the second roller part (353) engages with the rotation hole (351) that rotates in place according to the rotation of the cable (1), thereby stably positioning the cable (1) inside the clamping unit (300). In addition, the elastic support unit (350) may further include an elastic spring (354) configured to elastically support the rotation hole (351); and a support body (355) that supports the first roller part (352) and/or the second roller part (353) from the lower side and forms a receiving space in which the elastic spring (354) is received. As illustrated in FIG. 5, four elastic support units (350) are provided inside the clamping body (320) of the clamping unit (300), so that the cable (1) fixed by the clamping unit (300) can be stably fixed, and at the same time, the cable (1) can be easily fixed by responding to a predetermined angle of rotation of the cable (1).

A protruding sensor (360) according to one embodiment of the present invention may include a sensor body (361) formed of a flexible material having a predetermined elasticity and protruding from the inner surface of the clamping main body (320) to a predetermined length; and a sensing contact portion (362) provided at one end of the sensor body (361) and configured to perform leakage sensing and heat sensing for a portion of the cable (1) that comes into contact by providing a leakage sensing unit (3621) and a heat sensing unit (3622) in a portion of the portion.

That is, the sensor body (361) of the protruding sensor (360) may be configured to protrude inwardly from the clamping main body (320) by a predetermined length, and a sensing contact portion (362) equipped with both a leakage current sensing unit (3621) for detecting current and a heat sensing unit (3622) for detecting heat may be provided at one end of the sensor body (361). Accordingly, the fixing support force for the cable (1) passing through the clamping main body (320) can be reinforced by the protruding sensor (360) having a predetermined elasticity, and at the same time, leakage current and ignition of the cable (1) can be easily sensed. In addition, since a part of the sensor body (361) is configured of a flexible material having elasticity and a predetermined area can be bent, the cable (1) can be easily supported for each cable (1) having various diameters. However, although it is described in this patent specification that both the leakage sensing unit (3621) and the heat sensing unit (3622) are provided in a single sensing contact portion (362), this is merely an example for easy understanding of the present invention, and it is of course also included in one embodiment of the present invention a configuration in which either the leakage sensing unit (3621) or the heat sensing unit is provided in a plurality of sensing contact portions (362).

Referring to FIGS. 6 and 7, an underground distribution cable management control system (1000) using a cable fixing device (10) according to one embodiment of the present invention sets a detection control area for leakage current and ignition for each single cable (1) among a plurality of cables (1), and sets a detection control area for leakage current and ignition for each length region of a plurality of cables (1) through a clamping unit (300) that interconnects the plurality of cables (1), thereby implementing an effective leakage current and ignition detection control system for the cables (1).

More specifically, a cable management control system (1000) for underground power distribution using a cable fixing device (10) according to one embodiment of the present invention may include a detection control unit (400) configured to detect in real time a leakage current and a fire of each cable (1) fixed by a plurality of clamping units (300) and interlocked with a plurality of the clamping units (300); a storage unit (600) configured to store real-time detection information of the detection control unit (400); a main controller (700) configured to control the operations of a plurality of the clamping units (300), the detection control unit (400), and the storage unit (600); and a communication unit (500) configured to implement communication between the clamping units (300) and the main controller (700). For reference, although not shown in the drawing, each clamping unit (300) may be provided with a communication unit (not shown) for transmitting and receiving detection information from a leakage sensing unit (3621) and a heat sensing unit (3622).

For reference, the main controller (700) according to one embodiment of the present invention may be implemented as a processor, a microprocessor, a controller, a microcontroller, etc.

In addition, the storage unit (600) according to one embodiment of the present invention may be implemented as various types of storage devices capable of inputting and outputting information, such as a hard disk drive (HDD), a read only memory (ROM), a random access memory (RAM), an electrically erasable and programmable read only memory (EEPROM), a flash memory, a compact flash (CF) card, a secure digital (SD) card, a smart media (SM) card, a multimedia (MMC) card, or a memory stick, as is known to those skilled in the art, and may be provided inside the main controller (700) or in a separate external device.

The detection control unit (400) according to one embodiment of the present invention comprises: a device linkage unit (410) configured to be linked with each of the plurality of clamping units (300) and to assign a unique ID to each of the linked clamping units (300); an area generation unit (420) configured to generate a detection control area for the clamping units (300) that fix the same cable (1) and a detection control area for the clamping units (300) that are interconnected through mutual coupling between the first connection unit (330) and the second connection unit (340); an area mapping unit (430) configured to map the unique ID of each of the clamping units (300) assigned by the device linkage unit (410) to each of the detection control areas generated by the area generation unit (420); and the leakage sensing unit (3621) and the heat sensing unit (3622) provided in the clamping units (300) each of which has the unique ID mapped to each of the detection control areas. It may include a real-time detection unit (440) configured to detect leakage and ignition in real time for each of the above detection control areas through the unit (3622).

First, more specifically, the device linkage (410) may be configured to receive detection information including information about current and temperature sensed on the surface of the cable (1) by being communicatively coupled with the leakage sensing unit (3621) and the heat sensing unit (3622) provided in each of the plurality of clamping units (300), and may be configured to assign a unique ID to each clamping unit (300) including the leakage sensing unit (3621) and the heat sensing unit (3622) that transmit the detection information. Accordingly, the detection information of the plurality of clamping units (300) may be easily classified by unique ID.

In addition, the region generation unit (420) may be configured to generate at least one detection control region for the clamping unit (300) that fixes the same cable (1), that is, at least one detection control region for a plurality of clamping units (300) that fix the same single cable (1). For example, as illustrated in FIG. 3, when a plurality of clamping units (300) fix a total of three cables (1) in parallel at a predetermined interval, the region generation unit (420) may generate a total of three detection control regions by generating a detection control region for each of the plurality of clamping units (300) that fix the same cable (1) for each of the three cables (1). That is, the region generation unit (420) may generate at least one detection control region for a single cable (1) according to the total number of cables (1).

In addition, the region generation unit (420) may be configured to generate at least one detection control region for the clamping units (300) that are interconnected through the mutual coupling between the first connection unit (330) and the second connection unit (340), that is, a detection control region for a plurality of clamping units (300) positioned at the same length region among the plurality of cables (1) arranged in parallel. For example, as illustrated in FIG. 3, when a plurality of clamping units (300) fix a total of three cables (1) in parallel at a predetermined interval, the region generation unit (420) may generate a detection control region for each of the interconnected clamping units (300) that fix the same length region of each cable (1) (i.e., the length region of the cable (1) illustrated at the upper side in FIG. 3, the length region of the cable (1) illustrated at the middle side, the lower length region illustrated at the lower side, etc.). That is, the area generation unit (420) can generate a detection control area for each clamping unit (300) provided at each location along the length of the cable (1) extending in the longitudinal direction.

The fifth detection control area is generated by grouping the unique IDs of each of the plurality of clamping units (300) connected to each other to fix the second length area of each cable (1), and the sixth detection control area is generated by grouping the unique IDs of each of the plurality of clamping units (300) connected to each other to fix the third length area of each cable (1).

Accordingly, the underground distribution cable management control system (1000) using a cable fixing device (10) sets a detection control area for leakage current and ignition for each single cable (1) among a plurality of cables (1), and sets a detection control area for leakage current and ignition for each length area of a plurality of cables (1) through a clamping unit (300) that interconnects the plurality of cables (1), thereby implementing an effective leakage current and ignition detection control system for the cables (1).

Next, the real-time detection unit (440) according to one embodiment of the present invention may be configured to generate real-time detection information for each detection control area based on the detection information of the leakage sensing unit (3621) and the heat sensing unit (3622) provided in each clamping unit (300) to which a unique ID is mapped for each detection control area, and to detect leakage and ignition for each detection control area in real time through the generated real-time detection information. As an example, the real-time detection unit (440) may be configured to generate real-time detection information for the first to sixth detection control areas based on the detection information of the clamping unit (300) having a unique ID mapped to at least one of the generated first to sixth detection control areas, and to detect leakage and ignition for the first to sixth detection control areas in real time through the generated real-time detection information.

For reference, the components (410, 420, 430, 440) of the detection control unit (400) illustrated in FIG. 7 are merely exemplary components for explaining the operation, function, etc. of the detection control unit (400) according to one embodiment of the present invention.
